A:Byblis gigantea and Byblis lamellata are
found only in the Perth region of Western Australia.
As they are species with restricted ranges, they are at somewhat elevated conservation risk to to
habitat destruction from urban sprawl.

Byblis liniflora occurs in a large area of northern Australia. The rest of the
species in the Byblis liniflora complex live in a swath of land in northwestern Western Australia,
near Kununurra and Darwin. A species of Byblis also occurs in southern New Guinea, and while this is
usually considered to be Byblis liniflora, there is some speculation that
these plants are actually Byblis filifolia.
